When to buy and plant Hellebores/Lenton Rose?
As I was looking around my yard this afternoon, I realized that the area where I have some purple-to-light-purple Lenton Roses planted has a perfect place to plant several more Lenton Roses to make a wonderful display, maybe for next year. Is it too early to buy and plant them? I don't want to start from seed; I'm too impatient for that right now!
With the late freeze we got last year in April, would it be ill-advised to go ahead and plant now, or is the cooler weather better for establishing these plants? With us getting spring rains, I was thinking it would be better to plant now, or maybe the middle of April, in order to avoid the problems I had last year with a newly planted perennial garden that suffered greatly in the drought.
If I plant different colors of Lenton Roses in the same area, will they cross-pollinate and make a different color, or will they retain their original colors?
We've been in this house for 3 1/2 years and these plants were already established when we moved here. I don't know how old they are, but I thought they were supposed to multiply, creating colonies. Mine haven't multiplied, but rather have remained the same, although they have done well. Will they multiply or do I just need to plan on filling in bare areas with additional plants?
Thanks for your help!
