2010 Field Trials: Dallas Arboretum

Best in Show:

Lobularia ‘Snow Princess’
Proven Winners
Planted: 5/27/2010(Ground & Container)
What a plant! This Alyssum is covered in fragrant white flowers that spread 18″, and it really holds up to the heat! A must have spring through fall. This vegetative cultivar is perfect for a container or the landscape. Took the heat all summer long.

Top 5 Varieties Overall:

1. Euphorbia ‘White Manaus’
Planted: 5/27/2010
(Ground & Container)
There have been several new cultivars over the last few seasons, but in a side to side comparison ‘White Manaus’ stands out. Bright white flowers that cascade this 2 foot tall Euphorbia. Great in both containers or in the landscape!

2. Gerbera ‘Drakensberg Daisy’ Series
Plug Connection
Planted: 5/27/2010
I never thought that I would love a Gerbera in this region, but I have been converted! This series does not have issues with chlorosis and continues to bloom throughout our Texas summer heat. ‘Drakensberg Orange’ is the color that really stands out. The new era of Gerbera is here!

3. Petunia ‘Soleil Purple’
Planted: 3/15/2010
‘Soleil Purple’ is a Petunia unlike any other! This is a drought tolerant cultivar with wiry stiff foliage and small double purple flowers. ‘Soleil Purple’ has out lasted any other Petunia in trials the last two seasons by two or more months. If you have given up on Petunia give this one a try, just don’t over water it.

4. Echinacea ‘Hot Papaya’
Plant Noveau
Planted: 2009 (Perennial)
This is a must have in any landscape. ‘Hot Papaya’ is a mop head Echinacea covered with bright red to orange mango flowers early spring and will re-bloom throughout the summer if dead headed.

5. Salvia ‘Wendy’s Wish’
Planted: 5/27/2010
This salvia was one of our favorites in the Trial Garden for the last 2 years. ‘Wendy’s Wish’ is vigorous and covered in fuchsia pink flowers early spring through summer and grows to 4’x 4′ in a season.

Making The Decision To Produce Medical Marijuana

Should horticultural growers consider cultivating medical marijuana? That’s up to the individual grower, of course, and certainly a number of growers already have jumped in. We at Meister Media Worldwide, publishers of Greenhouse Grower and American Vegetable Grower, do not necessarily endorse nor oppose the production of medical marijuana. But we do feel it is an option worth exploring. We intend our “Medical Marijuana” series of articles to give you information you need to make your own call. We hope you find it useful, and we do welcome your comments, thoughts and ideas as we continue to cover what we’re fairly certain is only going to be an increasingly viable and growing market for this emerging crop.
