The Master
Gardener trip began with a Ferry ride to Middle Bass Island, a bus ride to
downtown Put-In-Bay and then a taxi boat ride over to Gibraltar Island. Once
the group arrived at Stone Lab, they
were greeted by John Hageman, Laboratory Manager and Associate
Sea Grant Extension Educator − Great Lakes. John shared the research and
teaching being done on the island and also gave a little history of the island
and its relationship to Ohio State. A brief history (from the website http://stonelab.osu.edu) of both the island and Stone
Lab is as follows: 

The Gem of Lake Erie. Gib. The Rock. Gibraltar Island has many names and a
long history. Originally a territory of the state of Connecticut, it was
purchased by New York banker Pierpont Edwards in 1807. Soon after, it became a
key in the War of 1812 when, on September 10, 1813, Commodore Oliver Hazard
Perry used the island as a lookout point to spot the approaching British fleet
before the Battle of Lake Erie.

Jose DeRivera, a New York capitalist, bought the island
from Edwards in 1854. In 1864, Jay Cooke purchased the island for $3,001 and
almost immediately began construction on the 15-room Cooke Castle, which still
stands on the island. The Cooke family visited the island at least twice each
summer for nearly 60 years, entertaining hundreds of guests, including Salmon
P. Chase, General William Tecumseh Sherman, and President Rutherford B. Hayes.

After the death of Jay Cooke in 1905, the island passed
into possession of his daughter, Laura Barney. The Barneys made frequent visits
to Put-in-Bay until 1925, when they sold Gibraltar to philanthropist and Ohio
State University Board of Trustees member Julius F. Stone.

Stone presented the deed to the island to the Board as a
permanent home for the Lake Laboratory. The Board accepted the offer and moved
to establish the lab on Gibraltar, changing its name from Lake Laboratory to
Franz Theodore Stone Laboratory after Julius’ father. The 21-room Laboratory
Building, Dining Hall, Stone Cottage, and Gibraltar House were completed in
1928, and classes were first offered there in 1929.

Stone Laboratory is the oldest freshwater biological
field station in the United States and the center of Ohio State University’s
teaching and research on Lake Erie. The lab serves as a base for more than 65
researchers from 12 agencies and academic institutions, all working year-round
to solve the most pressing problems facing the Great Lakes.

In addition to its role as a research facility, Stone Lab
offers 30 college-credit science courses each summer for undergraduate and
graduate students, advanced high school students, and educators. The hands-on
sessions get students out into the field or out on the lake to study courses
like biology, geology, and natural resources.

After the introduction to the island and Stone Lab, the
Master Gardeners saw first-hand some of the research issues being studied in
the exotic and invasive species class, learned about the make-up of the island
and its relationship to the environment through the island geology class and
finally had a chance to walk the island discovering all the edible wild plants
that grow on the island and in many of our backyards.

After a full day of education classes and touring the
island, Master Gardeners taxied back to Put-in-Bay and either continued their
tour on their own or headed back to the mainland on the ferry. It seemed to be consensus
that this had been a fun, yet very educational trip for all those who attended.

The Erie County Master Gardener Volunteers planned this
workshop/tour for their group and other Master Gardeners to have an opportunity
to learn more about the island and the lake. This is just one example of the
many opportunities that Master Gardener Volunteers have to learn about
horticulture issues and our environment. If you think you might be interested
in these same opportunities, please contact the OSU Extension office in Erie
County. There is a Master Gardener Training Class being offered this fall in
Huron County and we are planning to offer a class in Erie County this winter.
Both classes will meet during the evening for several weeks.

Before the yellowing...

Blanketflower is a great plant for hot, tough locations and is beginning to bloom in central Ohio. The large daisy-like flowers are often a combination of hot colors (red, yellow) and appear in early June and last for around 3 weeks. These plants tolerate hot dry soils and tend to be short-lived in moist, fertile soils. Heights are anywhere from 8-24″ and widths are 12-24″ depending upon the cultivar. Plant them in masses or groups in borders in full sun; they also tolerate light-shade. Common cultivars include ‘Dazzler’ (bright orange flowers with yellow tips, 24-30″ tall), ‘Goblin’ (red flowers with yellow tips, 12-15″ tall), and ‘Baby Cole’ (maroon flowers with yellow tips, 8-10″ tall). Plants should be deadheaded (dead flowers removed) as needed to prolong blooming. Divide plants every 2-3 years for best growth.

Now that the weather is finally cooperating, gardeners are planting lots of impatiens in shade gardens around Ohio! This easy-to-grow shade-lover does best in well-drained soils and in shade ranging from light to heavy.The more sun these plants get, the more water required to keep them healthy. Most of the newer cultivars don’t require pinching to make them bushy or deadheading (removing the dead blossoms). Plants grow anywhere from 6″ (pixie varieties) to 12-15″ tall. Flower colors are red, pink, orange, salmon, white, purple, and bi-color. The newer double cultivars are loaded with blooms compared to varieties from the past! Impatiens are relatively pest-free; however, it is a good idea to rotate them out of a flower bed every few years to avoid the potential for Verticillium wilt.

WEED – SPURGES (Euphorbia spp.). PROSTATE SPURGE (E. prostrate) and SPOTTED SPURGE (E. maculate) are prostrate summer annual weeds that reproduce from seed each spring but are most noticeable in July, August, and September. They may be identified by their white, milky sap and small, oval leaves, and a taproot. They have an open and prostrate mat-forming growth habit and branch freely from the base. Their reddish or green, prostrate stems form a mat-like growth that often chokes out desirable turfgrasses. They are commonly found growing in mulch, around the edges of a lawn next to curbs, driveways, sidewalks, and may be scattered through thinning, less vigorous turfgrass. Improving lawn care practices to encourage thicker grass cover will help control these weeds. The sap from both plants is a milky latex. Some people develop a rash after coming into contact with the sap. Plants can be easily pulled and bagged if soil is moist. Be sure to wear gloves to prevent skin contact with the sap.

This aquatic plant is the only lotus species that is native to the U.S. and Canada. It may be found in the backwaters of rivers and reservoirs, in pools in marshes and swamps, and in lakes. Native Americans used the seeds and fleshy rhizomes as food. The circular, deep green leaves range in size from 1-3′ and are flat if floating on the water surface or slightly cup-shaped if they rise on rigid stems up to 3′ above the water. Leaves lack slits which helps to distinguish this plant from water lilies. The showy, fragrant, pale yellow flowers are borne on stalks and may be 10″ in diameter with more than 20 petals. The inverted-cone shaped seed pod in the center of the flower has openings in which the seeds develop making the structure look like a shower head. Once petals drop, the seed pods droop down making them look even more like shower heads.

American lotus colonies spread by seeds and submerged rhizomes, and they may be propagated as bare root plants, and by rhizomes or seeds; the seeds must be stratified. The lotus plants provide a healthy habitat for a wide range of micro- and macro-organisms. The large leaves protect immature fish from predators, the seeds are utilized by ducks and other migratory birds, and the rhizomes are fed upon by beavers and muskrats. American lotus is listed as “threatened” in Michigan, and “endangered” in Pennsylvania and New Jersey. However, the plant is banned in Connecticut and is included on the state’s “Invasive Plant List.” Indeed, this species may become aggressive and difficult to control in shallow ponds and lakes throughout its native habitat.
