Why Do Hellebore Flowers Last So Long?

Hellebores are all the rage right now and everybody seems to be adding more to their garden. A big appeal is the fact that they flower so early, sometimes even when there is still snow on the ground. But the real reason people like them is that they bloom a very long time; as much as five months.

Or do they?

They certainly seem to bloom for a long time; a closer look will reveal their secret. Once you understand why they bloom so long you will be able to select other plants that do the same thing.

Ligularia przewalskii

Ligularia przewalskii is a great plant for part shade to heavy shade. It likes lots of moisture but does just fine with medium moisture levels. It has interesting toothed leaves and tall yellow flower spikes that contrast well with other shade plants. I cut it back the flower spikes after flowering and that is all the maintenance it gets. By spring, in zone 5, the leaves are on the ground and you can just leave them there. New foliage will soon cover them.

Do Trees Have A Heartbeat? – A Myth is Born

It is becoming popular to ascribe human characteristics to plants and the latest headlines say, Scientists Discover That Trees Have A “Heartbeat”. Imagine that, soon trees will be falling in love with each other.

Plants are extremely interesting organisms, but this habit of making them sound animal-like is confusing a lot of people. In a Facebook Group, gardeners started to question the harm we do to trees when we prune them – does it affect their heat? Do they feel pain?

This myth has a very clear beginning and illustrates how many modern day myths get started.

Do you want to grow gunnera but your climate is too cold? Then Astilboides tabularis is a good alternative. It has some of the largest leaves you can grow in colder climates and it makes a strong statement in any garden. Most people who visit my garden are unfamiliar with the plant and find it very exotic. Its leaves are an odd round shape that reminds one of an umbrella or table top. They easily reach 60-90 cm (2-3 feet) in diameter.

Barnardia japonica

Barnardia japonica is a lovely bulb that flowers in late summer, early fall, when most other rock garden plants are slowing down. The pink-mauve flower spikes are quite tall for such a small bulb, reaching about a foot. The flowers are very dainty, but are produced in numbers large enough to give a good display. As the flowers open, the flower scape elongates.

Foxglove (Digitalis purpurea monstrosa) Forms Peloric Flowers

I walked outside a few days ago and immediately spotted my monster foxglove. It is a cream yellow, growing in a fairly shady spot where the color just glows. But what made it really stand out is the large uncharacteristic flower at the top of the inflorescence (flower stem).

After a bit of work on the computer, I learned that this is a rare peloric mutation.

15 Moss Myths Every Gardener Should Know

I love moss on rocks and trees, and even growing on the ground, provided it is in the right spot – as determined by my aesthetic sensibilities. It is not nearly as welcome in the lawn although I don’t really mind having it there. Moss in the lawn is considered by many as a big problem and this has led to a number of myths about moss.

Some people try to grow moss, but that is not as easy as it sounds. Moss is kind of strange that way; some people are constantly trying to kill it, while others are trying to grow it.

My goal for this post is to understand moss better by exploring the many moss myths.
