Lavandula stoechas Otto
Quast has these fabulous pale purple rabbit ears and dark purple flowers. In
all other regards the plants grow just like the other Lavandula stoechas
cultivars. They are easy to grow, they stay low, they bloom for a
long time from Spring into Summer. Even longer if you have the
inclination to cut off all of the dead flower heads. Lavandula
stoechas has low water needs and is great for the Drought tolerant
garden. Spanish lavender will tolerate temperatures into the low
teens or even single digits.
