Has anyone grown St. John's Wort in full or mostly full sun? I wanted to get some for a certain spot, but the tags said shade/part shade.

In my area (9B, mostly) Hypericum calycinum will grow in sun or shade.
In a sunny location it requires regular water (we get no summer rain here). Even then it can sunburn.
In the shade it can get by with very little water.

Optimum way to grow it here:
Water through the summer.
Fertilizer (not much, but some)
Part shade from the hottest sun. Dappled light under trees is very good.
Mow it every year to every 3 years to get rid of the old, scraggly stuff and encourage new, lush growth. Mow it in February- the new growth happens in March.

Are there any plants that discourage snakes? If not, any other ideas? Carol7 35 Aug 23, 2007 12:37 AM
