Geranium psilostemon flower
In our Zone 7a garden:
This is a very favourite geranium. We enjoy an extremely long bloom time…from the end of May / beginning of June into the middle of October, even without dead-heading, and this was in spite of only receiving 8mm of rain throughout August and September in 2012. (Okay…we admit we did splash some water around the garden during that period of minimal rain.)

More Plant Descriptions!

by Leslie Cox; Saturday, October 13, 2012

I have added a few more plant descriptions to the list under “In the Garden – Plants We Grow section. Hope you like the photos!

You will notice the list is alphabetical so the latest ones are “muddled in”. Keep checking back as more plant descriptions will be coming now that the autumn rains have arrived and are forcing me to spend more time indoors. My arthritis is definitely not happy when the weather turns wet and cold. Thank goodness for the woodstove!

Hosta ‘June’

Hosta ‘June’    Family: Hostaceae
(HOSS – tah) Tardiana Group

Common name: plaintain lily
Zone: 3 – 8
Height: 15 in (38 cm)   Spread: 20 in (50 cm)
Aspect: full sun; partial shade; full shade
Soil: moist; fertile; well-draining
Water: regular

Description: An herbaceous perennial with mounding habit. Ovate leaves are bright yellow in the centre with narrow, irregular streaking of blue-green on margins. Highly scented panicles of lavender flowers appear on strong stems in July and August.

 

Special Notes: ‘June’ is the first tissue-cultured sport of Hosta ‘Halcyon’. Awarded Hosta of the Year for 2001 and for very good reason. This hybrid seedling has fairly good sun tolerance; yellow centre will be muted if sited in full shade. A medium-sized cultivar, it is reported to be rabbit resistant but not deer resistant. Watch for slugs and snails when leaf tips are emerging in early spring. Leaf spots and crown rot may be a problem.
