Hi.
It seems like you love sempervivum so much, you get naughty ideas. You know, I thought of ways you, and everyone can spread the love in safe ways. I used to be way more involved in my community.
1. Get involved with you local parks district.
a. Propose public installation you can work on. Local park or around municipal building.
b. Work on yearly public landscape areas, i.e. downtown/mainstreet district
c. Old Heritage Historic Houses and mansions could use some hort help and bed help
d. Local forest preserve sometimes have tiny gardens near clubhouses where classes are taught.
2. Start/join a local garden club or join Master Gardeners
a. Networking with other enthusiasts
b. Volunteer opportunities
c. Knowledge, both gaining and sharing
3. Join a secular place of learning or your local religious institution
a. Schools and community colleges could use volunteers to install perennial gardens with the children, teens, young adults involved. These are great for science classes.
b. Local museum, such as a science. Beds could be built into landscape
c. 'Tending the garden as an act of piety' Ask to build a garden on the grounds of your preferred religious or faith institution. They usually have way too much grass. Get others involved. Think of a prayer or meditation grotto.
4. Take the family to Europe and dedicate ones life to conservation of natural habitat.
5. Buy private land with lots of rock features, do what one desires.
6. Sponsor a garden with a local buisness
Good luck. Find local kindred spirits to share sempervivum love with. Our natural heritage is a treasure to be loved, cherished, and respected. It is fun to also do restoration projects or invasive removal. One should become familiar with the local ecosystems. Plus, no one wants to be 'that guy' who inadvertently brings the next watermillfoil, purple loosestrife, kudzu, Emerald Ash Boer, or chestnut blight.
