Hypericum kalmianum
Kalm's St. John's Wort
Sturdy small shrub that is covered with golden pom pom blooms in late June. Delightfully showy and absolute pollinator magnet! Strangers will stop and ask what it is. Habit is well branched and mounding plus it is very hardy. Fairly adaptable but you'll get more blooms with more sun and a decent amount of water. Blooms July-August.
