Q. Identifying a plant

My friend has a large plant in a pot outside. It has loads of small bright mauve blooms that look a bit like monkey flower, but the foliage has many small leaflets on a stem, and the flowers each have a thin stem about two inches long. The whole plant has an airy, dainty look to it. Beautiful.

The leaves you describe, with many leaflets on a stem, are known as "pinnate":

Most flowers that look similar to monkey flower are in the plant order Lamiales. One of the few plant families in Lamiales with pinnate leaves is Bignoniaceae, so perhaps your friend has one of those plants. Here are some examples:

Q. bignonia capreolata

My vine is 3 years old, and it’s the 1st year it’s going to bloom BUT the buds form but the flower is not forming. the tube is there but it doesn’t open, it just falls off. It doesn’t look like I have a bug on it. Any suggestions to help it along.

Training to avoid crowding of stems will aid in the formation of flower shoots. Branches can be cut back in the spring to encourage flowering.
Best flowering is achieved in full sun.
Water regularly to occasionally when actively growing in the warmer months for best results .

Thrips can be the cause of flowers just dropping form a plant. They can be difficult to see in some cases.
You can use Neem Oil if you suspect that pests are the cause.

Q. What Could Cause My Well-established Crossvine Plants (5 Of Them) To Up And Die?

Plants are against a cement wall; are on a drip watering system; have done fabulously for 3-4 years now (including through our long hot summers). Toward the end of August, one developed many dead parts and from there it has spread to adjacent crossvine plants. There does not appear to be any bug issue.

It sounds like the soil may have contracted an infection. Fungal/bacterial infections can come out of nowhere, but are usually the result of staying too wet for too long.

From here, you will want to treat with a fungicide. This article will help: https://www.gardeningknowhow.com/garden-how-to/info/using-fungicides-in-garden.htm

You may, also, want to use a handful of DOLOMITIC LIME per plant, and a teaspoon of WETTABLE SULFUR per plant. Cast this into the soil, and it will work itself in with a few waterings. This will help to take out any remaining infection, as well as condition the soil.
