Dandelions are another desirable/weed plant. While some mercilessly destroy all Dandelions, others convert them to wine. Years ago a friend had me try some Dandelion wine he had made. It probably would have been useful as a deer repellant. Our local Farmer's Market displays fresh Dandelion greens which are sold as people food. Then again we have some who abhor Broccoli and others, like me, who love it.
Jerusalem artichokes have, I believe, nice flowers. The crunchy tubers, "artichokes", are a useful addition to a salad or a stir fry. But be careful. While your back is turned they can multiply beyond both reason and your appetite. Even a small section of tuber left behind after a harvest will produce a new plant the following season.
Beware of "friends" bearing gifts of extra plants. First check to make certain that they are not invasive which may be why your "friend" has so many. Kay received a gift of some forget-me-nots. I foolishly planted them. Does anyone want a few thousand of them? They have gone wild. To humor Kay, a lover of miniscule flowers, I tried to retain a few. I should have destroyed them all when I still had the upper hand. No more. They crop up everywhere now.
The recent past has been one of extremes. First a week of unusual and record breaking April warmth with a high temperature of 89°F (32°C). Buds burst into bloom and everything turned green. Then an earthquake hit early one morning shaking the house. This was followed by more usual local spring weather, snow again and a hard frost. Gardening is a never ending challenge.
